01 - Pat salmon fillets dry with paper towels. Season both sides generously with kosher salt and freshly ground black pepper.
02 - Heat olive oil in a large, deep skillet over medium-high heat. Add salmon fillets skin-side down and sear for 3-4 minutes until golden and crispy. Flip and cook 1-2 minutes more. Transfer to a plate.
03 - In the same skillet, add chopped onion and cook for 2-3 minutes, scraping up any browned bits from the bottom. Add minced garlic, dried oregano, and chili flakes; sauté for 1 minute until fragrant.
04 - Stir orzo pasta into the skillet and toast for 1-2 minutes, stirring frequently until lightly golden.
05 - Pour in white wine and let simmer for 1 minute. Add broth, lemon zest, and lemon juice. Stir well and bring to a gentle boil.
06 - Reduce heat to medium-low, cover, and cook for 8-10 minutes, stirring occasionally, until orzo is just tender and most liquid is absorbed.
07 - Nestle salmon fillets skin-side down on top of orzo. Cover and cook for 3-5 minutes until salmon is cooked through and orzo is creamy.
08 - Remove from heat. Stir in butter and Parmesan until melted and incorporated. Sprinkle with chopped parsley. Serve immediately with extra lemon wedges.
